Hi all, I've been experiencing some trouble on an experimental server :

everything works fine, until someone tries to change his password. Thefirst ten users could change their password, but now, whenever they dothis, the "passwd" process locks up, can not be killed (tried kill -1 and-9), and subsequent calls to "sync" lock with the same symptoms.When shutting down the machine, worse things happen : the machine locks upafter printing "unmounting remote file systems". MagicSysRq-S does notwork (MSR-U does remount r/o, however. But that does not help anything). Needless to say, after rebooting, everything is fsck'd up, and on a 6 Gbdrive, it takes some time...

After a reboot, I tried to change a password under strace's control.Passwd locked itself up while calling "sync()", after succesfully changingthe password.

What puzzles me the most is that the first accounts didn't causeproblems...

(as a temporary workaround, I can use RH's control panel to change thepasswords, but that's neither confortable or a good long term solution).
